Method and device for realizing load balance

Abstract

The invention discloses a method for realizing load balance, which is applied to a wireless local area network comprising a wireless controller, a wireless access point (AP) and a wireless client (STA). The method comprises the following steps: scanning the AP in the wireless local area network regularly by the wireless controller to acquire the load information of the AP, and judging whether a load between a first radio frequency and a second radio frequency on the AP is balanced or not according to the load information; if the load between the first radio frequency and the second radio frequency on the AP is not balanced, examining whether the STA associated with the AP supports various radio frequency types or not by the wireless controller, and if so, adjusting the SAT which supports various radio frequency types to switch the radio frequency types. The invention improves the throughput of the whole network.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for realizing load balancing. Background technique [0002] As one of the hot technologies in the IT (Information Technology, information technology) industry at present, WLAN (Wireless Local Access Network, wireless local area network) provides a wireless connection service of a local area network, which can provide high-speed wireless data access, and is widely used in cities and Network coverage in public places, as well as various places such as enterprises, buildings and homes. [0003] In the WLAN office network and hotspot coverage network, some APs (Access Points, wireless access points) or all APs can provide two radio frequency services at the same time: 11a and 11g, and the difference between wireless clients is obvious, and some only support 11g, some can support both 11a and 11g. [0004] At present, the IEEE 802.11 standard does not make a...

Problems solved by technology

However, the algorithm used by STA to achieve load balancing is inconsistent among various vendors, which will lead to load imbalance between 11a and 11g.

In addition, the balance between 11a and 11g lacks a dynamic process. For example, after 11a and 11g reach a balanced state in a dual-frequency network, several single-frequency wireless clients are connected, which will still cause a problem between 11a and 11g. load imbalance
